Hi Team,

Below is our setup. And it can bring up our LVDS panel.

W 1024 H 768

Sync width 6

VBP 8 VFP 12

HBP 8 HFP 12

MIPI DSI 1chA 2 lanes input

LVDS output 1ch

24bpp

If we want to boost the frame rate to 60Hz, which register should be modify?

Data 50M*24 to MIPI Bridge

Regards,

Roy

Hi Roy,

With a different frame rate, the pixel clock rate will change, in turn changing the LVDS clock and DSI clock rates as well. To program the device please use the DSI tuner tool to generate the register settings.

Among other changes, it will change the register 0xB register clock divider/multiplier.

DSI Tuner: SN65DSI83: DSI TUNER tool needed
